in the video around 50 mins when node* is being declared why we need to write it as
node < T >*
and not just node*…
why we need to write< T > as it is the data type of value variable in the node…node itself cannot be of any data type…

hey @Prajawal-Pandey-2140320206067139, node is the name of the class(templated class here) which has T type of data. We have to specify the datatype while creating object or pointer to object when we are using templated class.

If you remember, while declaring vector of int type, we used vector v because vector can be of any datatype. Check STL of vector you will see vector v in declaration.

so can i create two classes with the same name node in a single program??
one templated and other with some fixed data type say int??

hey @Gaurav13998, No you cannot, when you try to create object for non templated class than compiler will expect templated argument(datatype)
